E8 PATENT LOUIS G. KLEESPIES, OF SAN FRANCISCO, CALIFORNIA.

SCREEN.

Application filed. May as, 1914.

To all whom it may concern:

Be it known that 1, Louis G. KLEEsrIEs, a citizen of the United States,residing at San Francisco, in the county of San l lllk cisco and Stateof California, have invented new and useful Improvements in Screens, ofwhich the following is a specification.

The object of the present invention is to provide an adjustable windowscreen which will eliminate flies and afford better ventilation than thescreens at present in use.

In the accompanying drawing, Figure 1 is a side view of the screen; Fig.2 is a vertical sectional view on the line 22 of Fig. 1; Fig. 3 is asimilar view on the linew33 of Fig. 1; Fig. 4 is a horizontal sectionalview on the line 4rt of Fig. 1.

Referring to the drawing, 1 indicates a screen frame, which may be ofwood, metal, or any suitable material. Its top 2 and bottom 3 are insections, one section having a dove-tailed rib 4 slidable in acorrespondingly shaped groove 5 in the other section. Thus the frameconsists of two sections movable horizontally to and from each other,each having one vertical side and two horizontal sides. In the inneredge of the vertical side 6 of each screen section is a groove 7 thewidth of which is slightly more than one-third of the thickness of saidvertical side, and in said groove are secured a series of cleats orclamping bars 8, 9, which clamp or wedge in the groove vertical edges ofa series of screen sections.

One vertical edge of the lowermost screen section 11 of each framesection is held between the clamping bar 8 and the outer side of thegroove 7. The next higher screen section 12 extends from a level aboutan inch lower than the top of the lowermost section 11, and a lower mainpart b of the corresponding edge of said section is contained betweenthe clamping bar 8 and the inner side of the groove 7; but the lowermostportion a of said edge is contained in an oblique groove 13 cut in theinner portion of the vertical side of the frame section. The extremeupper portion (Z of said edge of said screen section is containedbetween the clamping bar 9 and the outer side of the groove, while anupper intermediate portion 0 of said edge is contained in an obliqueoutwardly and upwardly extending slot or groove 14 formed by the obliqueparallel upper edge of the lower clamping bar 8 and lower edge of theupper clamping Specification of Letters Patent.

bar 9. A vertical series of as many screen sections as may be desiredmay be used in the screen in this manner. The uppermost screen sectionhas its corresponding edge clamped between the inner side of the groove7 and the uppermost clamping bar 9, the lower marginal portion of saidedge being, however, received in an oblique groove or slot 16 cut in theinner portion of the vertical side of the frame section.

The above described construction is the same for both frame sections andinasmuch as it is necessary that the screens of one frame section shouldslide inside those of the other frame section, the upper and lower edgesof the uppermost and lowermost screen sections respectively are receivedin grooves 17, 18 formed in the inner edges of the respective horizonalmembers of the two frame sections. The other vertical edges of saidscreen sections are clamped in narrow folded metallic strips 20,said-strips extending from the bottom of the screen sections, first, tothe upper edges of the lowermost screen sections, then being bentdownward to the bottoms of the next upper screen sections, and-beingthen bent upwardly to the tops of said screen sections, and so on inlike manner to the top of the screen. The upper edge of each screensection except the uppermost slides between, and is guided by, a bentportion of the metallic strip 20 clamping the edge of the correspondingscreen section of the other frame section.

My improved screen tends to eliminate flies from a room in which it isused, for the tendency of the fly alighting on the screen is to walkupward thereon, and in doing so it eventually arrives at the openingbetween two screen sections, and, passing through said opening, is thenoutside the room. lVforeover, my screen affords better ventilation,especially in calm weather when it is most needed, for, under suchconditions, the only air currents are those produced by the heating orcooling of immediate objects, and in such cases they are vertical, andsuch air currents are very greatly obstructed by the old style ofscreen, whereas by my improved screen they are facilitated.

I claim A window screen composed of sections and having the top andbottom made in sections slidable relatively to each other, each framesection having therein a vertical se ries of screen sections, the upperportion of each lower screen section extendmg above, and outside of, andbelng spaced from, the

lower portion of each screen section above edges of the screen sectionof the other frame section.v a
